1. Selecting the Language/Country

When you go to the Internet Archive you’ll see a long, long list of links to the various files that used to be available from apple. You’ll notice there are multiple versions of both System 7 and System 6 on the site for the various languages supported by the OS, you’ll need to select which one you want to work with. For this guide I’m going to select the English north american versions.

2.2. System 6.0.8

3. Setting up Basilisk II to copy the System files on to one of my drive image files

I’m assuming you’ve already downloaded one of my image files that you plan to update, and you’re using an emulator (Basilisk II, SoftMac etc.) to update the image file. As I mentioned in my post for creating drive images you can NOT use HFVExplorer to directly edit the images I provided, I instead use the My Computer option in Basilisk II to copy files on to my emulated drives. BUT you can use HFVExplorer indirectly by creating a partition image file and copying the files on to that new image, and then adding that file as a secondary volume.

I’m going to summarize the Windows approach for using my drive images. For this example I’m going to use the 100 MB Zip drive image file with the minimum version of 7.5.5 already installed (but this process will work for any of the 7.5.5 image files I’ve created).

4. Updating the System files

At this point you should have downloaded the sea.bin files from the archive (section 2 above), have Basilisk II running and be able to navigate to the folder on your system containing the downloaded files from the archive. For this example I mapped my Drive D: on my windows machine to the This PC icon in Basilisk II, and navigated to an folder called “OS” I created that holds all of the System files (Figure 4).

Figure 4: OS folder

You’ll need to “unwrap” the .bin files. The .bin extension indicates that the files have been MacBinary encoded, if you know about classic Macintosh Systems and how they store files you already know why, if not, you can read up on Resource Forks to learn why these files have to be wrapped (encoded) for transfer over the internet.

4.1. Installing System 7.5.3

Create an Installation Folder in Basilisk II on OS 6.0.8 and 7.5.5 drive and select “This PC” and then copy the installation files from section 2 in to the Installation Folder you just created (Figure 5)

When you set up Basilisk II (BasiliskIIGUI) you should have mapped one or more drives on your PC to the “This PC” icon.

Open the OS 6.0.8 and 7.5.5 drive and under Utilities you will find a copy of Stuffit Expander 5.5 (Figure 6)

In your Installation Folder select all the files except file 01 of 19 and drag and drop them on to the Stuffit Expander 5.5 icon.

I used Edit “Select All” then hold down the Shift key and click the first file to deselect it.

If you get the message “The shrink wrap engine has reported an error” then you accidentally included file 01 of 19. Try again without including it. I believe if you include the 01 of 19 file in the original drag and drop then StuffIt Expander tries to both unwrap and expand this file, but to expand it StuffIt needs to append the other 18 files, because the remaining files aren’t yet unwrapped StuffIt can’t find them to append so it throws an error. By unwrapping the 02 to 19 files first you avoid this issue.

Now select the file 01 of 19 and drag and drop on to the Stuffit Expander 5.5 icon

An icon called Sys7.5 V7.5.3 CD Inst should now be on your Mac Desktop (Figure 7)

Run the installer

You will see a message: The Installer cannot update the version of Macintosh System Software on the disk named "OS 6.0.8 and 7.5.5". Please remove the System Folder on "OS 6.0.8 and 7.5.5" and try again.

Use the Switch Disk button to select your TempDisk as the destination drive

You will now see a message: Click Install to place system software version 7.5.3 on the selected disk.

Hi deniz, you should be able to:
– config your SCSI2SD drive so drive 1 is the same size or greater than your current drive, and so it has a scsi ID of something other than your current boot disk, see step 3.1 http://www.savagetaylor.com/2018/01/05/setting-up-your-vintage-classic-68k-macintosh-using-a-scsi2sd-adapter/#comment-6031
– connect your SCSI2SD to the external scsi port on your Macintosh IIVX
– initialize the disk using LIDO or a patched version of HD SC Setup 7.3.5 (if you don’t have these, they are on my images, you can initialize your SCSI2SD with one of my images first, so you can copy the file off on to your old drive, then repeat these steps with the setup you want)
– once initialized copy everything from your current drive to the SCSI2SD drive(s) (I say drives because you may have setup multiple partitions for yourself)
– turn off your computer, disconnect your old drive.
– config your SCSI2SD drive with the SCSI ID your old drive had
– connect your SCSI2SD drive internally (in place of your old drive)
– turn on your Mac.
